SPIDER Automation 4mm Gold-Plated Female Battery Connector | Low-Resistance Power Connection | For Batteries, Brushless Motors & ESCs
Description
The SPIDER Automation 4mm Gold-Plated Female Battery Connector is a compact high-current electrical connector designed for reliable power connections in battery-powered equipment and power electronics. With a 4mm inner diameter, female configuration and precision-machined construction, it provides a practical interface for connecting compatible battery wiring, brushless motors, electronic speed controllers and other DC power equipment.
The connector is manufactured from brass with gold plating to provide a durable conductive contact surface. Its sprung contact construction is designed to maintain secure electrical contact when properly mated, while the low-resistance connection supports efficient current transfer. The rear-side cut design provides additional access for soldering, making wire termination more convenient during electrical assembly and system integration.
With a compact 20.5mm length, this female connector is suitable for applications where a high-current connection is required within a relatively small wiring space. It can be used with battery systems including 3500mAh or larger battery configurations and in systems specified for 80A+ operation, provided the complete electrical system—including wire gauge, battery, connector pair and termination—is appropriately rated for the required current.
